The. rails es inrlieuted in Figure il, and the left hund side of Figures l and 2, are for lriillie Coming toward fhe reader. For triil lie wing away from the render es Shoxyr m right hemleide of "Figures l mul QJhc-l rolzilzive positions olif 'rails A. :und la are changed so that,y ruil. i3 is nl; the left und rml lll) loo

lill' A at the right, and upper surface .14 is at the extreme left and surface 9 at the extreme right,`as will be clear. The exact position of the vertical iin 8` in relation to the base and the comparative relations of the areas on the upper surfacemay be modified by such considerations as the character of the traiic which the rail will be eigpected 'to support, and the maximum rigidity for a given weight of steel.

Considering a pair of rails, as for instance A and B in Figure 3, the rails are laid parallel, but each with the wide overhanging upper tread portions 9 and 12 disposedkon the left side of the vertical fin 8. Similarly the groove or depression 10 and 13 ofieach rail is formed on the right side of thefupper tread portion. It. will b e seen that the ange of a metallic wheel is received'lin each groove, with the v longitudinal axis of the trolley car. equidistant from each groove, although not equidistant relative the upper plane surfaces of the rails.

Thus trolley cars may travel on each pair of adjacent pairs of rails, and ample clearance is provided between them for safety. When trucks or buses travel. on the upper plane tread surfaces of the rails, the centers thereof, longitudinally may beappreciably to the right of the center line of a trolley car as positioned on the same rails, and still the resilient tires will have ample traction on i the tread surface of the rails and without 4:ses

contacting with the angular 1portions of the rails adjacent the grooves. his lateral displacement afforded by the rails enables two arge trucksfon opposed or adjacent tracks or rails 'to ass with perfect freedom and without stri ing. 1

Obviously the spaces between the rails maybe, and should be filled with a desired medium substantially in the plane of the tread surfaces, upon w'hieh as desired operators of motor vehicles may swing out from the tracks for passing a slower vehicle in the front, when 1t may again return to the tracks or rails. In this connection an item of expense that has heretofore been of considerable importis practieall elminated by this invention. This is the eterioration of theroadbed usually for perhaps a foot on each side of the rails, incidentto the ounding strain to which it is subjecte when motor vehicles are half on and half oi the rails, and the half oi is carried by the adjacent paving. This condition maintains disintegration of the paving adjacent therails is largely reduced as the rails are wide enough to receive and su port the entire weight of the motor vehic es.

It will be noted that my -improved'unitary rail is suehas can be formed by a single rolling in the mill, is strong enough for any use to which it may be ut, and has a tread portion of great smoot ness'over any ortion of which resilient tires may` run wit a minimum of wear, and yet which also guides and holds the flanged wheels of trolley cars.

I claim as my invention:

l. The combination of two rails arranged in parallelism, the entire upper surface of each rail being substantially plane and in the' plane of the. other substantially exce t for a longitudinal groove formed in eac the plane area of each rail forming aV motor "chicle tread receiving surface on the same side respectively of said groove, the tread of onerail also being arranged to support a fianged wheel the iange ot which is guided in the groove, and a shoulder vin the plane of the tread receiving surface of the other rail but on the opposite side of the roove from said tread to support another anged wheel the flange of which is guided in the groove of said other rail.

2. The combination of two rails, each of said rails having an upper tread portion substantially in the same plane, and each having a longitudinal groove in the tread portionat the same side respectively of the eenters of said tread portions, and so arranged that the longitudinal axis or center line of trolley cars or trains guided by the grooves is spaced laterally an appreciable distance from the longitudinal axis of motor vehicles supported on said tread portions;

3. The lcombination with two pairs of rails, each rail of v-a. pair having an upper tread portion and a longitudinal groove arrange toward the sameside respectively of each rail, each pair being reversely disposed relative the other, and the whole so arranged that trolleys or trains passing over said rails are given a predetermined clearance between the pairs of rails, and further so that motor vehicles passing over said rails are accorded substantially the same clearance even though wider than said trolley or train. v

In testimony whereof I affix my signature.
